The DRV8374-Q1 provides a single-chip power stage device for customers driving 4.5V to 35V brushless-DC motors. The DRV8374 integrates three 1/2-H bridges with 40V absolute maximum capability and a very low RDS(ON) of 17mΩ (high-side plus low-side) to enable high power drive capability. Current is sensed using an integrated current sensing feature which eliminates the need for external sense resistors. Power management features with integrated LDO generate the necessary voltage rails for the device and can be used to power external circuits.
DRV8374-Q1 implements a 6x or 3x PWM control scheme which can be used to implement sensored or sensorless field-oriented control (FOC), sinusoidal control, or trapezoid control using an external microcontroler. The DRV8374 is capable of driving a PWM frequency up to 200kHz. The control scheme is highly configurable through hardware pins or register settings ranging from motor current limiting behavior to fault response.
There are a large number of protection features integrated into , intended to protect the device, motor, and system against fault events. Refer for design consideration and recommendation on device usage.
